Asset scan credential Library

Asset scan credential Library

Hi all, 

new to service desk plus, and just starting out config the asset management e.g setup probes

a bit lost in setup of the credentials library. have added the basic snmp public and windows one.

work on some but not other.

Does anyone have a standard cheat sheet for this. e.g if certain printer then use this, if multifunction device then use this, if portable barcode scanner, then this.. etc..
